Abstract
Stark measurements have been made on persistent IR spectral holes in the stretch mode of the CN−:Na+ center in KBr. A simple model in which the anharmonic CN− molecule is coupled harmonically to the lattice qualitatively explains both the magnitude of the zero-field frequency difference for the two molecular arrangements in the crystal as well as the absence of a Stark tuning curve for one of these configurations.
